Im here once again and once again need help ! (Amnesia Custom Story)

[BesTCracK]

I will say it to you like this for example we have got Oil , Blood potion : Blood potion I put to a chemistry thing ( vial or something ) then to it Oil = result new potion ( for example its name is Unfinished Potion )
then the Unfinished Potion I want to mix with ( lets say with a potion I found somewhere else for example Uncompleted Acid ) I want to mix Unfinished Potion with Uncompleted Acid by putting them into a extaction oven and when I put them in it will make new potion ( for example Acid ) and I will pick the Acid .

For this I want to do the script I posted you the script here but the only thing that doesnt work is that the last potion ( Acid ) doesnt appear
